i was thinking you know because am3 cpus have both a ddr2 and ddr3 controllers on chip i wonder if it would be possible to run both at the same time if the motherboard had ram slots for both ddr2 and ddr3. i doubt it would work but what if it actually did? intel just came out with triple channel ram if this worked it could possibly be quad channel. or it could be used as a large low latency cache. lol idk im just dreaming right now.
edit: from the amd k10 white papershmmm what does inbetween mean? like if the memory controllers were ganged and both channels share the same memory controller? or is it possible to run 2 different ram types in unganged?The DCTs do not support different DRAM types (DDR2 and DDR3) on the same channel or between channels.

Well, I got banned from their forum for pointing out that there was a flaw in a couple of their reviews, so this comes as no surprice to me.
Back on topic: I suppose a motherboard like the new ECS would make Deneb shine the brightest:
"ECS today releases their A790GXM-AD3 motherboard, which is Socket AM3 ready, and thus 45nm Phenom II + DDR3 memory ready.
ECS today releases the A790GXM-AD3 Black Series motherboard disclosing the extraordinary gaming performance of AMD’s latest Dragon platform. Supporting the latest AMD Phenom™ II processors, ATI CrossFireX™ technology, and the dual channel DDR3 memory architecture, ECS A790GXM-AD3 unleashes the full potential of hardware components that gamers are always eager for. With its upscale capability, the A790GXM-AD3 motherboard brings a spectacular gaming platform delivering the irrefutable performance to satisfy the gaming desire of extreme gamers.
Inheriting the advantages of AMD 790GX chipset, the A790GXM-AD3 Black Series motherboard incorporates the support for the latest 45nm AMD Phenom™ II processors to deliver the next generation computing capabilities. In addition, ECS A790GXM-AD3 comes with the feature of dual channel memory architecture that supports DDR3 1333MHz memory up to the capacity of 32GB which is capable to provide faster data throughput for memory-intensive applications. To meet hardcore overclockers’ requirements, the latest exclusive BIOS utility, M.I.B. II, is included to provide various detailed tweaking options. Paired with AMD SB750 south bridge controller supporting the function of ACC (Advanced Clock Calibration), ECS A790GXM-AD3 allows users to push the overall system performance to another higher scale. As the key factors that eventually decide the stability while overclocking, the 5 phase power design"

It's weird why brands are putting out AM3 boards when there's 1 month left for the AM3 cpu's to arrive to the market ...
... this makes me think ...
... maybe that question about PII am2+ being compatible with AM3 boards ... maybe that's not so out of the book as we thought...
I just have a hard time thinking that a company, in these days where economic turndown is the main focus when planing a selling strategy, puts a AM3 board to sale and they know that, at the moment, the sales will be very very low due to the non existence of AM3 CPU's...
I'm still trying to fight through my ideas and believes and decide if i go with i7 or PII ...
For one side the power i7 ... but the price of de i7 is way to high ( yes, i am willing to pay for it, but if can save some money... best for me )
The other side, PII ... a old passion for AMD cpu's and the unclear performance makes me apprehensive
letsssss wait and see
Oh...your ass is grass and I've got the weed-whacker.
am3 where's on HT3.1 mentioned on that board?
the am2+ chips and the am3 chip should have the same exact ht speeds. ht 3.0 has a max hyper transport speed of 2.6ghz. i have always thought that the only difference between the two chips was one supported ddr3 and ddr2 and one supported ddr2. http://www.hypertransport.org/defaul...Specifications

so just because everyone was curious about am2+ cpus using ddr3 i asked about it. k10 does infact have a ddr3 controller on it but am2+ cpus can not use it because it is disabled through fuses. so i asked if am2+ cpus could work in am3 motherboards. he wasn't sure but he said if it would work it would not work with ddr3. so even if am2+ cpus would work in am3 motherboards the am3 boards would have to have ddr2 memory slots.
edit: so im doing a google search for fuses on k10 and i get this from our own forums from last year when k10 was first released: http://www.xtremesystems.org/forums/...&postcount=699. it also states that there is a ddr3 controller but it is disabled through fuses.

IF the AM2+ Deneb works in AM3 motherboards, as someone has claimed, then it would be because of the following:
(DISCLAIMER: This is based ONLY on my opinion and a guess)
There might not really be a "true" AM2+ Deneb. All DENEB chips might be AM3 chips that will work on AM3 or AM2+ motherboards. They may just release the first couple of chips before AM3 motherboards are available and say that they are AM2+ Denebs for marketing purposes.

FX-8350, Powercolor ATI R9 290X LCS, OCZ Vertex 4, Crosshair V Forumula-Z, AMD Radeon DDR3-2133 2x8Gb, Corsair HX1000W, Thermaltake Xaser VI, Xonar D2X, Water Cooling 140.3
So why they dont make all PH2 backward compatible with am2+?
they all should work in am2+. even the am3 version.
might be possible since i really don't understand why they made an am2+ version. hell if the am3 one can do both and they are both physically the same cpu but the am2+ version has the ddr3 controller disabled then they should both cost the same to manufacture. my only guess why they made an am2+ version is because they were planning to have a larger launch gap between the am2+ and am3 cpus and the am3 ones weren't quite ddr3 ready. if they have both an am2+ deneb and an am3 one i wouldn't be surprised if they stopped making the am2+ one after the am3 launch.
MERRY X-MAS EVE YOU MUDDA'XS'ERS!![]()
I thought that HT3.1 is Orochi/Bulldozer(32nm) features.
Besides i don't think HT3 is bottlenecked yet so no improvements for desktop because of HT3.1.

I think that ! AMD will go to 22nm with Orochi/Bulldozer.
Great, AMD going to go 32nm 2011. Unless they can improve their 45nm process quite a bit, there is no way AMD can compete against Intel, considering that Intel has way better fabrication process compared to AMD, not to mention smaller node(With Immersion Lithography?) in 2010.
Basically AMD has two advantages regarding current leakage, SOI and IL, while Intel has HKMG. Intel 32 nm will be far superior to anything AMD will have until 2011, and probably even until AMD gets their 32nm process working. Basically AMD is at it's best with PhII in 2009, and after it, well, PhII will be quite like PhI is right now - thrashed by any Intel QC. Though, that applies only if AMD can not improve PhII much during 2009/early 2010. I doubt they can do more than new silicon revisions which are not going to save them against Intel's very fine tuned and mature 45nm process.
Then again, I doubt AMD are going to live with 45nm for that long. They desperately need to close the gap with Intel in order to become competitive again. Even if AMD has superior Uarch, superior manufacturing process, Intel will hold the market share no matter what. They can produce so much more than AMD can that they can sell their chips for lower prices and still make profit. There is no way for AMD to counter this, other than getting more chips produced, meaning that TFC needs a lot more fabs.
Call me a fanboy or idiot or whatever you want, but thats how I see it. In terms of manufacturing CPU's, Intel is unbeatable by anyone. They are the best at it.

little early to predict amd's future. as we know anything can change at any time as seen by the 4870 even tho those weren't the performance leader they still came out ahead over the 280 because of its price. phenom II could end up the same way and it has been showing promise in what we have seen so far.
